I currently take loratidine, meloxicam, ranitidine, doxycycline, spironolactone, and just two days before the ua test my doctor took me off of tomazapam, and put me on seroquel. Could any of these show positive for Methamphetamine? They also said that my last ua test line was light for meth also as well as my 11 year old son who also takes claritin when needed? I also take an o-t-c multivitamin and probiotic, I have also been having to use an inhaler called Dulera, and a nasal spray called fluticasone propionate, because of a cold and an o-t-c generic nasal decongestant which contains phenylephrine HCL - 10mg per tablet.
